SDE 2

Calfus Inc.

  • Lead frontend architecture, design system, and product delivery across all 5 enterprise clients on the mvue.ai platform.

Jan 2025 - Apr 2026

Associate Software Engineer

Calfus Inc.

  • mvue.ai – Cash Flow Optimization Platform (Founding & Sole Frontend Engineer)
  • Sole frontend engineer for 1+ year — architected and built the frontend from scratch on a multi-tenant, multiapplication platform now running in production across 5 enterprise clients.
  • Designed and shipped 31 production routes across 12+ feature modules spanning the cash-flow workflow — including AI-agent audit trails, denial management, and analytics — on Next.js (App Router) with TypeScript strict mode.
  • Built multi-tenant Keycloak SSO with per-tenant realm resolution, vault-based credential lookup, JWT session refresh, and federated logout — isolating identity and data across all tenants.
  • Engineered a real-time streaming UI for AI agent calls using Server-Sent Events — custom ReadableStream parser, event-driven Redux sync, and full stream lifecycle handling.
  • Implemented role-based access control with dynamic feature flags and category-level permission assignment across 13 tenant-scoped application areas.
  • Built 15+ enterprise data grids on AG Grid Enterprise with virtual scrolling, server-side pagination, multi-column filtering, and XLSX export — handling tens of thousands of financial records per view.
  • Designed and shipped a custom design system of 40+ shared components and 20+ Radix-based UI primitives on Tailwind CSS 4 — the foundation every module is built on.
  • Owned the frontend state and quality stack: 54 Redux Toolkit / RTK Query slices, structured Pino logging, Vitest + RTL with >80% test coverage, and Husky pre-commit gates.
  • Collaborated on core system design including database schema modeling, microservices architecture, and integration patterns for agentic-AI workflows.
  • Drove frontend performance: reduced heavy-route bundle size from ~6MB to ~2MB uncompressed (~65%) by lazy-loading AG Grid and other heavy dependencies behind route-level code splits.
  • Background Check Platform (Enterprise Client)
  • Maintained and enhanced an enterprise background-check platform; designed, developed, and shipped a candidate adjudication module that streamlined background-verification workflows.
